Abstract

一种摄像灯，使用氙气灯作为摄像用人造光源，其工作电路上依次连接有蓄电池，升压电路，所述升压电路输出端分别经高压点火电路和转换电路连接至氙气灯，所述氙气灯输出的灯管电压和电流经控制与驱动电路处理后再同时反馈给上述升压电路和转换电路。

Description

摄像灯
技术领域：
本实用新型涉及一种摄像与摄影用人造光源。
背景技术：
在一般摄像机中，为了可在光线较弱条件下进行摄像，需要有一个与摄像机主体相连的单独摄像灯。传统摄像灯一般采用石英灯、碘钨灯、卤钨灯等钨丝灯等作为人造光源，其发热量大，电能转换成无用的热能白白浪费，不仅光效能低，并且灯具严重发热，可能对使用者造成伤害。另一方面，由于耗电量大，所以电池的一次充电后的使用时间短。如果要延长使用时间，必须使用体积和重量都很大的电池。钨丝灯的使用寿命也短。所以造成使用不便，难以在摄像机中推广。
发明内容：
本实用新型目的在于提供一种节能性好，结构合理，适应性良好，使用方便的摄像灯。
本实用新型的特征在于，使用氙气灯作为人造光源，其电路上依次连接有蓄电池，升压电路，所述升压电路输出端分别经高压点火电路和转换电路连接至摄像用氙气灯，所述氙气灯输出的灯管电压和电流经控制与驱动电路处理后再同时反馈给转换电路和升压电路。
本实用新型所涉及的新的摄像灯优点在于：1、电光转换效率是传统摄像灯的六倍，也就是说，如果同样的光强度和同样的电池，该装置的使用时间是传统摄像灯的六倍。2、即使电源电压较大幅度的波动，仍然有稳定的光强度输出。3、发热量低，不会对使用者造成伤害。4、灯管和电路的抗震能力强，不怕震动，氙气灯的使用寿命是钨丝灯的十倍以上。5、该装置可以使用更小的电池，使用更便于携带。
附图说明：
图1为本实用新型工作电路的原理方框图。
具体实施方式：
下面结合附图对本实用新型予以具体描述。
本实用新型特征在于其工作电路上依次连接有DC12V蓄电池，DC/DC升压电路，所述DC/DC升压电路输出端分别经高压点火电路和DC、AC转换电路连接至摄像用氙气灯，所述氙气灯输出的灯管电压和电流经控制与驱动电路处理后再同时反馈给上述DC/DC升压电路和DC/AC转换电路。DC12V蓄电池能量耗尽以后，由12V充电器为其充电。
